Abstract: TITLE OF THE INVENTION TUBE EXPANSION APPARATUS            ABSTRACT OF THE DISCLOSURE     An apparatus for expanding a tube against the walls of a circumscribing bore, or a sleeve within a tube to effect an interference joint therebetween, is described herein. The tube expansion apparatus generally comprises a fluid mandrel connected to a hydraulic expansion unit for applying a radially expansive force to the tube or sleeve, and a control circuit electrically connected to the expansion unit and fluidly connected to the mandrel for sensing fluctuations in the pressure of the fluid discharged from the mandrel during the elastic and plastic deformation of the tube or sleeve during the expansion process, computing a final swaging pressure on the basis of these pressure fluctuations, and deactuating the hydraulic expansion unit when this final swaging pressure is attained within the tube or sleeve. The invention is particularly adapted for minimizing or eliminating the clearance between the heat exchange tubes of a nuclear reactor, and the baffle plate bores through which they extend. The invention may also be used to generate interference joints between such heat exchange tubes, and a reinforcing sleeve inserted therein.

Abstract: ABSTRACT OF THE DISCLOSURE     A slide fastener stringer tape is held in a substantially vertical plane between a pair of openable punch dies with coupling elements having legs mounted on the stringer tape and coupling heads disposed downwardly of the punch dies.  The coupling elements are gripped vertically between the punch dies, and a punch and a pair of punch guides.  The punch dies are moved laterally away from each other to spread the legs apart from each other out of engagement with the stringer tape.  The punch has a sharp upper end for thrusting into the coupling heads to split the coupling elements into scraps.  Alternatively, the punch has a rounded upper end for pressing engagement with the coupling heads.

Abstract: PISTON ASSEMBLY FOR A REFRIGERANT COMPRESSOR            ABSTRACT OF THE DISCLOSURE   A piston assembly for a reciprocating piston type compressor includes a piston slidably disposed within aluminum alloy cylinders. The pistons have two annular grooves provided toward opposite ends on their outer peripheral surfaces. A conical shaped piston ring formed of resin and having an outer diameter larger than the outer diameter of the piston is disposed in each groove. The conical shaped piston ring creates a gap between the piston and cylinder to prevent direct contact between the piston and cylinder to thereby avoid abnormal wearing while effectively maintaining the flow of lubricating oil from the cylindrical chamber to the crank chamber.

Abstract: ABSTRACT OF THE DISCLOSURE An initial condensate of phenol resin containing a foaming agent and a curing agent is put into a mold by coating, spraying or other means in such a manner that a layer of uniform thickness is obtained.  An aggregate such as  perlite  is  then  put  into  the  mold.    The  initial condensate  is heated  to cause  foaming  so that the gaps between particles of the  aggregate  are  filled  with  the phenol resin which is being foamed and cured to obtain an integrated body.  Thus, a flame retardant composite phenol foam having an aggregate dispersed therein and having no voids between the particles of the aggregate is prepared.

Abstract: ABSTRACT      A process for recovering tobacco particles from intact cigarette packages in which the intact packages are subjected to disintegrating action effected between impeller members and one or more pairs of longitudinally extending rows of teeth, of which the teeth in each row project transversely toward the teeth in the adjacent row, each impeller member having its cross-section elongated in the longitudinal direction and moving generally longitudinally relative to said rows.  The disintegration may be carried out on a modified tobacco threshing machine and is effective to tear the packages and paper tubes of the cigarettes containing the tobacco particles into a mixture comprising tobacco particles and non-tobacco fragments which are substantially larger than the tobacco particles.  This allows the resulting mixture of non-tobacco fragments and tobacco particles to be separated to obtain tobacco particles which are substantially free of non-tobacco fragments.

Abstract: Abstract of the Disclosure:       In coding a digital video signal representative of successive pictures by using correlation between the successive pictures, each picture is divided into a predetermined number of blocks of picture elements.          An original motion vector is used to represent a movement of each block between two pictures.  The digital video signal is predictively coded by using the original motion vector to produce a coded signal.  The blocks are processed into an on-off control signal.  A part of the coded signal is subsampled into a subsampled signal with refer-ence to the on-off control signal and a remaining part is left as it is as a non-subsampled signal.  The subsampled and the non-subsampled signals are code-converted into a converted code signal.  The original motion vector and the on-off control signal are code-converted into a converted motion vector signal and a converted control signal.  The converted control signal specifies transition points which appear in the on-off control signal when the on-off control signal is switched between off and on.
